Previous Next 5 of 5 Be careful

This thickened toenail has been trimmed correctly. The toes next to it need a similar straight cut. After the toenails have been trimmed, gently file the edges with an emery board or nail file. This removes sharp edges or corners that could catch on your socks.

See your doctor if:

  • Your thickened toenail embarrasses you
  • Your thickened toenail is very painful
  • You don't think you can trim your toenails safely on your own
